The 'frog eBike 2012' is Straight Out of TRON

The 'frog eBike 2012' by Jin Seok Hwang is a concept for a motorcycle that is completely electric and far too futuristic for today's streets.

Where a normal motorcycle would have a bulging engine, this bike has a hole, which Hwang says is a "symbolic void." Underneath the void lies the bottom chassis which is where all the battery cells are stored. To charge them, one must plug the bike into a charging station and wait for the battery cells to become full. By putting the battery cells under the void, it makes the bike extremely balanced and creates for a smooth ride.
